Last year many forage sorghum fields were heavily infested and damaged by Sugarcane Aphid (SCA) (Figure 1) – Melanaphis sacchari – feeding. Most calls came in around early July of 2016 with reports of aphids that were not well controlled using broad spectrum materials such as malathion, chlorpyrifos, or dimethoate. This triggered investigations which confirmed the invasion of the new species of aphid to California.
Based on field research and extension material from the US states in the South and Southwest, some basic guidelines for spotting, scouting, and treating SCA can be outlined for potential best management practices in our CA forage sorghum production system.
Identification:...

Bees are the most important pollinators of California agriculture—helping us grow field crops, fruits, nuts, and vegetables. Honey bees receive most of the credit for crop pollination, but many other kinds of bees play an important role as well. There are 1600 species of bees in California! Take time during Pollinator Week to learn about the different kinds of bees and what you can do to help them flourish.
Why should I care about other kinds of bees?
Bees other than honey bees contribute significantly to crop pollination. For example, alfalfa pollination by alfalfa leafcutter bees is worth $7 billion per year in the United States. Other bees can also boost the result of honey bee...
